Soo first of: "between 74% and 209% more performance-per-dollar" I think you mean between 74% and 109% more.
Second: Good for Intel to boost their ego by beating last-gen AMD. I'm sure Threadripper 3 will be on-par with this if not even faster.

So have Intel and AMD traded places with there over exaggerated claims? I'd guess that this will be on a specific work load and will not take into account both next gen tr and the guaranteed requirement to need a new socket.
Trying to do the maths on this basing it on the current 2990wx is £1500 but struggling whilst I'm at work but it looks as if it's going to have to clocked significantly higher, priced a lot lower or contain a hell of a lot of cores if not all to reach those claims

Intel has been speaking a lot about "real world" performance. Ultimately it depends on what they test. Threadripper can fall short in a lot of applications due to its multi-die nature. That said, Threadripper beats Skylake-X in Intel's numbers, so it must be a mix of factors.

AMD plans to release the Ryzen 3rd Gen 3950X soon, so that is the new 16-core that Intel needs to compete with. It is only a matter of time before Threadripper is replaced.

Between Ryzen 3rd Gen and next-gen Threadripper Intel needs to decrease their pricing of X299 hardware. This way, Intel has spoken about their price cuts early so that it is seen positively. They don't want this to be seen as "we are reacting to AMD".

My 3900x at stock with a dodgy BIOS has about double the performance of my overclocked 2700x in Cinebench despite my 3900x only having 4 more cores. AMD would have to really screw up badly with Zen 2 Threadripper to not see them have a similar uplift over Zen+ Threadripper...
